Change Description

Adding support for CAPI for the new crypto primitives and C++ api support for SHA3/Keccak and the new get_block_num functions.

[ ] API Changes
CAPI now has the functions:
void sha3( const char*, uint32_t, char*, uint32_t , int32_t)
int32_t blake2_f(uint32_t, const char*, uint32_t, const char*, uint32_t, const char*, uint32_t, const char*, uint32_t, int32_t, char* , uint32_t)
int32_t k1_recover( const char*, uint32_t, const char*, uint32_t, char*, uint32_t)
int32_t alt_bn128_add( const char*, uint32_t, const char*, uint32_t, char*, uint32_t)
int32_t alt_bn128_mul( const char*, uint32_t, const char*, uint32_t, char*, uint32_t)
int32_t alt_bn128_pair( const char*, uint32_t)
int32_t mod_exp( const char*, uint32_t, const char*, uint32_t, const char*, uint32_t, char*, uint32_t)
uint32_t get_block_num( void )

The C++ API now has the functions:

block_num_t current_block_number() - this is in system.hpp
eosio::checksum256 sha3(const char*, uint32_t) - this is in crypto.hpp
eosio::checksum256 keccak(const char*, uint32_t) - this in crypto.hpp
void assert_sha3(const char*, uint32_t, eosio::checksum256&) - this is in crypto.hpp
void assert_keccak(const char*, uint32_t, eosio::checksum256&) - this in in crypto.hpp
